Air Compressor Controller For Screw Compressor MAM 860 CT Sensor

Faults in the electrical control systems of screw air compressors often don't occur suddenly during operation, but rather are a gradual, cumulative process. A sensor signal may be intermittent, or the contact resistance of a relay contact may slowly increase. By the time the compressor finally shuts down, troubleshooting can take several times longer than normal maintenance. The MAM-860 CT is designed around the core logic of "comprehensive protection and early warning." The controller integrates multiple motor protection functions, including phase loss, overload, current imbalance, overvoltage, and undervoltage protection. It also features real-time three-phase current detection (with a matching CT transformer interface), one PT100/PT1000 temperature input (configurable as compressor head temperature or exhaust temperature), and one 4-20mA pressure transmitter input, providing comprehensive signal acquisition capabilities. When the actual temperature exceeds the set value, the current is abnormal, or the phase sequence is incorrect, the controller automatically executes shutdown protection and simultaneously displays the fault code on the Chinese and English LCD screen, greatly reducing troubleshooting time.
